HEEL FOR BOOTS AND SHOES.

Specification of Letters Patent.

Patented July 7, 1908.

Application filed January 24, 1908. Serial No. 412,474.

To all whom it may concern:

Be it known that I, SAMUEL BURNI-IAM, of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in Heels for Boots and Shoes, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

This invention relates to certain new and useful improvements in heels for boots and shoes, and it has for its objects among others to provide a simple and improved heel made up in parts or sections, the lower part, that subjected to wear in walking, being made removable so as to be replaced by a new portion when worn, yet rigidly held in position so as to prevent accidental displacement. The lower or removable part may be made in one, two or more sections, the object of which is to provide for the removal of that portion only of the heel that is badly worn and the replacing it by a new perfect portion. As it is sometimes the tip of the heel portion and at other times the outside of the heel near the tip that is most worn, the advantages to be gained by making the removable portion in sections will be apparent and readily appreciated.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention, in its preferred forms, is clearly illustrated in the accompanying drawings which, with the numerals of reference marked thereon, form a part of this specification and in which Figure 1 is a side elevation of a portion of a shoe showing the improved heel applied thereto. Fig. 2 is a substantially central vertical longitudinal section through the heel. Fig' 3 is a bottom plan of the heel with the lower, or removable portion detached. Fig. 4 is a section on the line 44 of Fig. 2 looking down. Fig. 5 is a top plan of the removable portion detached and formed in sections. Fig. 6 is a similar view showing another form of removable portion. Fig. 7 is a detail, partly in section and partly in elevation, the section being on the line 77 of Fig. 6.

Like numerals of reference indicate corresponding parts throughout the several views.

Referring to the drawings 1 designates a portion of a shoe of any well known or pre ferred form of construction.

2 is the upper portion of the heel, made up of any desired number of layers or lifts of leather or other suitable material, as seen in Fig. 2, and this portion is designed to be secured to the sole of the shoe in any of the well known ways, not necessary to herein illustrate. Next below the portion 2 is the portion 3 which is preferably of metal in the form of a hollow shell, as seen best in Fig. 2, having preferably a marginal flange 4 around its upper edge, as seen in said Fig. 2, for the purpose of affording a better support for the upper portion 2 of the heel. This shell is provided with openings 5, in this instance shown as two in number and through which pass ordinary wood screws 6, as seen in Figs. 2 and 3, the said screws, as seen in Fig. 2, passing into one or more of the lifts or layers of the upper portion 2 of the heel.

Mounted to slide within the shell and upon the bottom thereof is a plate 7 having upon opposite sides notches 8 within which screws or other securing means 6 are received, as seen best in Fig. 4. This plate is actuated by a spring 9 at the point of the shell, the said spring finding a bearing at one end against the end wall of the shell and at the other end against a wall 10 formed by bending up a portion of the movable plate 7 and forming a housing 11 for the spring, the end 12 of said housing forming a stop to engage the end wall of the shell to limit the inward movement of the movable member, as will be clearly understood upon reference to Figs. 2 and 4.

The bottom wall of the plate 3 is provided with a plurality of perforations 13, shown in Fig. 3 as being six in number, although it is evident that this number may be varied under varying circumstances and conditions. The object thereof will soon be made apparent. The movable plate is provided with a plurality of perforations 14, in this instance shown as six in number, for cooperation with the perforations in the bottom wall of the shell. The movable plate may be guided in any suitable manner and held against vertical displacement, in this instance being shown as movable beneath a bar or member 15, extending lengthwise of the shell and over the movable plate, the said bar or member being held in position by a lu 16 extending upward from the bottom of tlie shell and through a longitudinal slot 17 in the movable plate, a suitable key 18 being employed, as seen in Figs. 2 and 4, to hold the bar or member 15 in place, it being understood that there is sufficient room between the said bar or member and the bottom wall of the shell to permit the free and easy movement of the plate 7.

The plate 7 has a projecting portion or lu 19 projecting through an opening in the enc 20 of the shell, as seen best in Fig. 2, the said projecting member having a portion 21 which extends beneath the flange 4 of the shell, as seen in said Fig. 2, to form a guide therefor and prevent its upward displacement.

In Fig. 3 there are shown projections 22.

rigid with the shell upon opposite sides of the projecting part 19 to shield the same and to prevent accidental inward movement of the movable plate which might result in loosening the removable part of the heel.

23 is the lower or removable portion of the heel, that which comes in contact with the ground and which is subjected to wear in walking. This may be made up of a single piece or any desired number of layers, as seen in Figs. 1 and 2, or, as seen in Fig. 6, formed of two parts 24 and 25 separable along the inclined line 26, as seen in Fig. 5, composed of the three parts 27, 28 and 29 separable along the lines 30 and 31. This lower portion of the heel is provided with a lurality of pins firmly secured therein, as or example as shown in Fig. 7 wherein the pin 32 is shown as having a screw threaded end 33 by which it may be screwed intothe leather, having a slot 34 if desired for the application of a screw driver or like implement. hen the lower part is made in one piece, three of such pins ordinarily will be all that will be required. When composed of two or three parts, as seen in Figs. 5 and 6, siX pins are preferably employed, as seen in said views. When of two parts three pins are provided in each part. When of three parts, two pins in each part, the pins in both instances being disposed in the same position relatively to each other so as to properly engage the perforations in the bottom of the shell and in the movable plate. The pins are notched, as shown at 35, see Fig. 7, for a purpose which will soon be made apparent.

In practice, the upper portion 2 of the heel being fixedly secured to the shoe and the shell 3 secured to said upper portion, by pressing inward upon the projecting por tion 19 of the movable plate, the latter is moved toward the point of the heel, against the tension of the spring 9, so that the perforations of the plate and of the shell are brought coincident with each other, the notches 8, which receive the securing means 6, permitting of said movement, and the end walls thereof serving to limit the movements curely lock the lower portion against removal. The forward openings in the plate are shown in Fig. 4 as open at their forward ends but this is not necessary.

From the above it will be seen that when the lower portion becomes worn it can be readily removed by pressing inward on the projection 19, which forces the movable plate to the rear, and when the perforations of the plate and shell are coincident, the lower member 23 can be easily and quickly removed and a new one substituted therefor. When the lower member is made in sections, as in Figs. 5 and 6, any one section thereof may be removed and a new section substituted, without replacing the whole of the lower member.

Modifications in detail may be resorted to Without departing from the spirit of the invention or sacrificing any of its advantages.
